Home Internet Overheating
This is primarily a reference post related overheating. If you want to read my full background, see the link at the bottom.
The Nokia device seems to have an overheating issue. For me that mean things would run fine for a few hours or even days and then suddenly speeds would drop so low it appeared to be completely offline. Even though the ambient temperature in the room was in the 60s and the device itself never felt that warm, adding a couple cooling fans drastically improved air flow throughout the device and completely resolved my issues. Here's a link to the fans I purchased.

You may only need one but since these came as a set I put one beneath the device and the other one on top. This has ensured constant airflow throughout the device and kept my modem from having any issues. I am fairly certain that the tower I am connected to does not support 5G but I have been very happy with my consistent 4G speeds that average around 100 Mbps download and 50 Mbps upload.

Jlillard, like you, I've found heat buildup to be a big (and maybe the main) issue. I've posted a description of that on another thread but will paste it below for convenience. In my case I simply placed the gateway on an A/C vent. To what you've said here, I would add that offloading the wi-fi to a separate router, avoiding 5g speeds, minimizing number of supported devices and concurrent usage, problems during big file transfers, can ALL be symptoms of a thermal problem. Add to that the fact that ambient temperatures are on the rise this time of year and….well you obviously get it. Thank you for posting some of the best info I've seen here. Following is that referenced post:
I think it's a thermal issue, and that's likely why T-Mob hasn't fixed it. My gateway had required a reboot almost daily. It behaved similarly to other accounts here in that my connection speed would drop to almost nothing (say 400kbps down) which to a person used to over 50mbps would look like a hard crash, but I haven't seen that yet. My best speed is 60mbps down and I'm delighted if I can sustain 10. Per speedtest, when the problem manifests I see a slight increase in latency but a massive increase in packet jitter, sometimes approaching a full second. Rebooting the gateway clears this condition. Now, thanks to a couple of astute posts here, I decided to test the heat theory. Placing a hand over the unit during normal operation I didn't detect much heat coming out, but when I placed it over an A/C duct directly beneath the sill it had been on, I felt a gush of almost hot air come out the top. This is extremely suspicious and tells me that the convective cooling the EE's had counted on isnt happening. My gateway hasnt required a reset since i moved it to the top of that a/c vent 4 days ago. There's probably a good reason the installation manual mentions not placing the gateway in direct sunlight and I wonder if the manual's been edited in that regard. I hope others here will replicate and report the heat test. Perhaps then T-Mob will stop stonewalling this issue.
